Whenever I remove the Adventure Backpacks mod, my game crashes again, and I seem to get an error for Enhanced Biomes on my crash report then. If I remove both of them, my game works perfectly fine. I have tried updating and downloading from other sites the Adventure Backpacks mod, but my game still crashes. Is there anyway I can keep Adventure Backpacks mod without making my game crash every single time?
